1 ERNEST J'. LIEBETRAU, OF NILES, MICHIGAN, ASSIGNOR T0 THE KAWNEER COMPANY, OF NILES, MICHIGAN, .A CORPORATION OF MICHIGAN wrnnow CONSTRUCTION Application filed July 14, 1930. Serial No. 467,770.

This invention relates to window constructions, and more in particular to a novel double-hung window construction, in which y the sash members and the frame are constructg ed as a unit, and adapted to be assembled in a structure, such as a ship, etc.

Among the objects of the present invention is to provide novel sash constructions slidable in a frame. The invention comprehends the construction of suoli slidable sash mem bers of metal, both of which are slidable upwardly to provide an opening of desired size.

A further object of the invention is to provide a window construction in which the lower sash may be raised through its entire height, and if it be desired to provide an opening of greater size, all that is necessary is to continue to raise the lower sash, such A lower sash carrying along therewith the uplo per sash, so that both sashes may be raised to provide an opening of the combined size of said sashes, or an opening of any intermediate size.

A still further object of the invention is to f provide means on an upper sash adapted to be engaged by a part of the lower sash whereby when the lower sash is raised to an extent substantially equal to its height, a further raising or opening of the lower sash, causes an engagement of said part by the lower sash and raises the upper sash to any desired height.

Another object of the invention is the provision of a novel window frame and sash construction, the window structure being built as a unit and adapted to be placed in a ship or building opening, and there mounted or held in position.

Another object of the invention is to pro- L vide a novel construction of sash member provided with a. removable top rail for fa.- cilitating glazing of the sash.

Further objects are to provide a construction of maximum simplicity, efficiency,

and maintenance; and such further objects,

economy, and ease of assembly, operationv bination, construction and arrangements of parts illustrated in the accompanying drawing, and while I have shown therein a preferred embodiment, it is to be understood that the same is susceptible of modification and change, without departing from the spirit of the invention.

In the drawing;

Fig. l is a View in side elevation disc-losing the exterior of the window construction.

F ig. 2 is a fragmentary view in vertical cross section taken in the plane represented by the line 2-2 of Fig. l.

Fig. 3 is a fragmentary view in horizontal cross section taken in the plane represented by the line 3 3 of Fig. l.

Fig. 4 is a fragmentary view in side elevation of the corner of the sash member.

Referring more particularly to the drawing, the embodiment selected to illustrate the invention comprises the hull or metal plate l of al ship, in an opening` of which is mounted the window frame designated generally as 2, and in which are slidingly arranged an upper sash member 8 and a lower sash member 4. rlhe window frame 2 is shown as comprising a sill 5 mounted upon a stool 6 and connected to a metal trim 7 as by means of bolts or rivets or the like 8, the metal trim in turn being connected by any suitable means to the hull or metal plate l stiles 9 which are adapted to be suitably connected at their interior to a j amb or wooden trim 10, and at their eX- terior to a metal trim 1l which is connected by means of bolts, rivets or the like l2, to the metal plate or hull of the ship; and a head jamb 13.

Connected also to the frame and forming a part thereof, is a head plate 14 connected by means of bolts. rivets or the like l5 to a metal trim 16, which in turn is connected to the metal plate or hull of the ship. This head plate 14 bridges between the stiles 9, andv at its lower edge is provided with a channel or groove member 17, adapted to receive a part of the upper sash 3 when in closed position.

The upper sash member 3 comprises an upper channel shaped rail 18 having an outwardly extending doubled-over portion 19 provided with a downwardly projecting rib saV CII

` on the head plate 14 so as to provide a tight i5.- closure therebetween when the upper sash is in closed position. The lower channel-shaped rail 22 of the upper sash member is constructed similar to the upper rail and includes a doubled-over inwardly extending portion provided with an upwardly extending rib 24 adapted to form a weather-tight closure with the upper rail of the lower sash 4. The side rails 25 are similar in construction and comprise a channel shaped rail having an outwardly extending doubled-over portion 26 adapted to be received in a longitudinally extending U-shaped groove or channel 27 in the stile 9.

The upper rail 28 of the lower sash 4 is similar in construction to the rails 18 and 22 of the upper sash, and comprises a channel shaped member having an outwardly extending doubled-over portion 29 provided with a downwardly extending rib 30 forming a channel therebetween and a side wall of the rail.

The lower rail 31 and the side rails 32 are similar in construction to the side rails 25 of the upper sash member, the side rails hav ing an outwardly extending doubled-over portion 33 adapted to be slidingly received in a U-shaped groove or channel 34 formed in the stiles 9. The Ushaped channels or grooves 27 and 34, extend for the full length of the Stiles, thus permitting upper and lower` sash members to be raised to a position adjacent the head jamb 13. The doubled-over portion 35 of the lower rail is adapted to abut against a shoulder 36 of the sill 5, and to seat in a channel or recess 37 in the sill.

In order to reenforce the sash rails and to permit the use of lighter material therein, the bottom rails and the side rails of each of the sash members is provided with a reenforcing bar 38 fitting conformably therein. In order to permit proper expansion and contraction of the glass 39 in the upper and lower sashes, channel shaped sections 4() of felt or the like are placed intermediate the glass and the reenforcing bar. The top rails 18 and 28 of the upper and lower sash members are made removable so as to permit edicient glazing of the sash construction. The side rails and top rails are cut on a bias as at 41, and a bolt, screw or the like 42 is adapted to be passed through counter-sunk openings in the upper sash rail and to threadingly engage in the reenforcing bars 38 in the side rails. Since these bars are rictionally held in tight engagement in the rails, the upper rails may not be removed without a removal of the bolts 42. Strips oit felt 43 are embedded in the top rails and engage the upper edge of the glass 39.

Felt or other weather stripping 44 is provided in each of the channels formed on the top and bottom rails wherever the same engage eaeh other or with the window frame, so as to provide a weather-tight seal when the sashes are in closed position.

The sashes are so constructed that the upper sash 3 may not be raised without also raising the lower sash, while the lower sash may be raised independently to a position where the top rail contacts a striking bar or projection 45 connected to the top rail 18 of the upper sash by means oi' bolts or the like 46. If it is desired to raise the lower sash beyond this position, such lower sash, by reason of the contacting engagement of the rail 28 with the striking bar 45 will also raise the upper sash 3. By reason of this construction, it is possible to provide an opening through the window extending from the sill V5 to the head plate 14, without any obstruction therebetween. Catch or locking members 47 provided with a plunger adapted to seat in openings in the stiles 9, permit the lower and upper window to be adjusted to various heights and there held in place by the catch members 47.

In order to permit the sash members .to be raised to their uppermost position, the window frame is provided with a Well 48 intermediate the head plate 14 and wood trim 49, and the head jamb 13.

Although the invention disclosed has been described as adapted for ship construction, it is of course to be understood that the same is admirably adapted for use in other structures wherever a unit or self-contained window assembly having a double lift sash construction is desired.

Having thus disclosed my invention, I claim:
